Patented Aug. 30, 1932 UNITED STATESy PATENT OFFICE ARTHUR W. WERNER, 0F MILWAUKEE, WISCONSIN', ASSIGN OR TO KIECKHEFER CON- TAINER COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATION OF MAINE Application led May 18,

This invention relates to improvements in sheet handling devices.

VIn box making devices, where sheets of material are discharged from a machine with a certain side facing upwardly, it is sometimes necessary to have said sheets conveyed to another machine with the reverse side facing upwardly.

It is, therefore, one of the objects of this invention to provide an improved sheet handling devicehaving means for intercepting sheets of material as they are being discharged from a machine and for depositing said sheets on a conveyer with their reverse sides facing upwardly. A further object of this invention is to provide a sheet handling device having means for engaging said sheets after they have been .turned over to properly aline the same on a conveyer preparatory to delivery to another machine.

VA further object of thisinvention is to v provide a sheet handling device which is simvple in construction and operation, and iswell adapted for the purpose ,describedl With the above and other objects inview1 the invention consists of the improved sheet handling device, and all itsparts and combinations, as set forth in the claims, and all equivalents thereof.

' In the accompanying drawing in which the same reference numerals designate the same parts in all of the views:

Fig. 1 is a side elevation of the improved sheet handling device, showing it in attachmentwith a box making machine, parts being broken away; and y Fig. 2 is a plan view thereof.u

Referring tothe drawing, the numeral 5 designates a box making machine having a driveshaft 6 journaled transversely therethrough. The said drive shaft has sprocket wheels 7 and 8 mounted rigidly thereon, the latter being connected by an endless chain 9 with a sprocket wheel l0 rigidly mounted on the sha-ft llof. a motor'12. y`

Extensions 13, from each side of the machine carry bearings f 14. A shelf 15 has trunnions 16 and 17 extending from each end thereof,'the said trunnions having their 1929. Serial N0. 364,197.

outer ends journaled in the bearings 14. The trunnion 16 carries a rigidly mounted spreeket wheel` 18 which is connected by an endless chain 19 with the sprocket wheel 7 on the shaft 6. A shoulder 20 is provided along one longitudinal edge on one side of the shelf, and a similar shoulder 2l is provided along the opposite longitudinal edge on the other side ofthe shelf.

Bearing stands 22, extending upwardly from the floor have a shaft 23 journaled therein. One end of a conveyer platform 24 is pivotallyL carried by said shaft as at 25. Arms 26, having elongatedv openings 27 therein are adjustably connected to the sides of the platform near its other end by means of bolts 28 which extend through the said elongated openings. The other ends of the arms 26 are in the form of bearings through 'which the trunnions 16 and 17 of the rotatable shelf extend.

Sprocket wheels 29, which are rigidly mounted on the shaft 23 are connected by endless chains 30 with sprocket wheels 31 mounted on a shaft 32. The said chains pass beneath chain tighteners 33 and through slots 34 in the platform 24. Pusher bars 35, for moving the sheets, are carried by said endless chains.

Another sprocket wheel 31 on the shaft 32 is connected by a short endless chain 30 with a sprocket wheel 32 rotatably mounted on a short shaft journaled below the platform. rlhe said endless chain travels in a slot 34 in the platform, and is provided with lugs 35. A pulley 36', mounted rigidly on one end of .the shaft 23 is connected by an endless belt 37 with a pulley 38 rigidlymounted on a shaft 39, the latter shaft being joui-nailed above the platform in bearings 40. Near the other end of the shaft 39, another pulley 41 is rigidly mounted, the said pulley being connected by a belt 42 with a pulley 43 mounted rigidly on a shaft 44. The latter shaft has its lower end rotatably carried byL a gauge ybar 45. Gn the lower end of the shaft 44 another pulley 46 is rigidly carried, the said pulley extending through an opening in the side 47 of the gauge bar 45. Near the other end of the gauge bar, a pulley 48 is rotatably Side of the belt extending on the other side.

The gauge bar has forked extensions 50, through which bolts 51 extend to adjustably secure the gauge bar in a desired angular position with relation tothe side of the plat-^ form 24.

A drag member 52, having an upwardly curved end portion, is loosely carried by the shaft 39. j z' A motor 53 carriesr a rigidly mounted s rocket-wheel 54 on the end of its drive shaft, the said sprocket wheel being connected by an endlesschain 55 with a sprockety wheel 56 rigidly mounted on an end of the shaft 23.

In the operation' of the device, the sheets of material which are discharged by the machine with one side facing upwardly, are intercepted by the rotatable shelf 15, the forward edge of the sheetengaging lthe shoulder of the shelf as indicated by the dotted lines in Fig. 1. As Vthe shelf turns over, the sheets are deposited on the conveyer platform 24v Ewith their reverse sides facing upwardly. Next, the sheets are engaged by one of the pusher` bars and lugs 35 and carried beneath the upwardly curved end of the drag member 52. As the sheets arc not in proper alinement on the conveyer, when dropped by the rotatable shelf, the gauge bar has been provided. The endless `belt 49 of said gauge bar engages the side edge of each sheet'a-nd pro erly alines'the sheet on the conveyer ac- 'cor ing to the angular position of adjustment of said gauge bar, ready to be fed to another machine.

In order to carry the side of the sheet to 'said gauge bar,tl1e short chain 30 has been provided. This Ylatter chain 'prevents the side of the sheet from dragging and throwing the sheet out of alinement and carries said side until it is in proper position to be guided by the gauge bar.

Although only the preferred form of sheet handling device has been shown kand described, it is not desired to be limited thereto, 'as the broad concept of the invention conktemplatesall changes and modifications as may fairly kcome within the lscope of the claims. Y invention disclosed but not specifically claimed herein, form subject matter of co'- `pending' application Serial No. `364,293.
